If you are facing huge battery drain/poor battery life in your galaxy device, here is the solution.
Go to settings, apps, and disable background data and battery use of the apps using high battery or all if possible. I disabled all and also disabled unwanted apps. And I am getting a very great result. My battery is almost double than before. I am so happy. You can also do some more things. Like data saver, location turn off, changes in permission manager that you can find in privacy section in settings.
